The Digital Time Display (DTD) with Day of Year (DOY) is a versatile, multi-featured, timecode-driven clock display. The unit is capable of displaying multiple formats of date and time including: 3-digit DOY, 12-hour (with PM indicator) time and 24-hour time as hh:mm:ss. These devices decode IRIG-B and SMPTE linear/longitudinal timecode (LTC) formats to function as clocks. IRIG-B decoding supports the 1 kHz modulated and unmodulated formats. SMPTE decoding supports 30 f/s, 25 f/s and 24 f/s, NDF (non-drop frame). Standard power connection and BNC connection for the LTC are provided. All configuration of the TCD is available via the USB interface and a Windows-based application TCD set. Configurations made with the USB port will be retained during power cycles.
